Title: Key telephone system
Inventor: ISHIKAWA HIROYA
IPC: H04Q3/58
Filed: 1988-02-04
Abstract: PURPOSE:To attain the secret conversation function of a key telephone set and a hold transfer to an independent telephone set without interference from the independent telephone set by separating the independent telephone set from a trunk line when the key telephone set is in use and attaining to receive a hold tone with the independent telephone set when it is held. CONSTITUTION:When a hold action is executed during the use of a key telephone set 3b, the hold data are received by a reception circuit 12 and a hold generation is transferred to a micro processor(MP) 11. The MP 11 turns on the contact 13a of relays 13 and 14. Simultaneously, the hold tone is generated from a hold tone source 15 by the MP 11, inputted to a trunk line 2 through an amplifier 16, insulation transformer 18 and the contact 13a and the hold condition is attained. On the other hand, contacts 14a and 14b are switched from a trunk line 2 to an extension feeder circuit 22 side by a magnetization. Next, the receiver of an independent telephone set 4 is lifted up, the relay contact 14b is switched to an amplifier 17 side, the hold tone is sent from a hold tone source 15 to the telephone set 4 and it is found to be in hold. when the key telephone sets 3a and 3b are not in use of the trunk line, the telephone set 4 can be transmitted.

Abstract: PURPOSE:To prevent disconnection of wires on a semiconductor device by forming shallow separating layer groove on reduced pressure epitaxially grown layer on a p-type substrate having an n<+>-type buried layer. CONSTITUTION:A thin n-type epitaxial layer 12 is formed by means of reduced pressure epitaxially growing process on a p-type silicon substrate 11 provided selectively with an n<+>-type buried layer. With an oxide film 13 as a mask the n-type layer 12 is selectively etched to retain thin layer 12 on the bottom of the groove. Then, an opening is selectively formed at the oxide film 13 to diffuse B in shallow depth and to simultaneously form an isolation region 14 reaching the subsrate 11, a base layer 17 and a resistance layer 15. Then, an emitter layer 18 and a collector layer 19 are provided as ordinal method, and aluminum electrode wire layer 16 is provided thereon. With such a structure the buried layer is not dispersed to the layer 12 to form the thin layer 12. Thus, the shallow groove may be enough to result in no disconnection of the wires on the groove.

Title: Machine structural parts of high strength and manufacture thereof
Inventor: ISOGAWA KENJI
IPC: F16C33/12
Filed: 1984-02-14
Abstract: PURPOSE:To increase the fatigue strength of machine structural parts of high strength by subjecting a steel consisting of specified weight percentages of C, Si, Mn, P, etc. and the balance Fe with impurities to induction hardening. CONSTITUTION:A steel consisting of, by weight, 0.30-0.80% C, 0.40-2.0% Si, 0.40-2.0% Mn, <=0.010% P, <=0.030% S, <=0.030% O and the balance Fe with impurities is subjected to induction hardening. C regulates the surface hardness, Si regulates the machinability, and Mn regulates the deoxidation, hardeability and machinability. Since the P and S contents are reduced, the sensitivity to quenching crack is improved to increase the upper limit of the C content. As a result, the strength as well as the surface hardness is increased, and the fatigue strength is remarkably increased. When specified frequency is applied, the life of a gear is remarkably prolonged. It is a matter of course that the fatigue strength is remakably increased.

As a result, the generation of errors included in the output timing of the ON/OFF combination of the switching elements 8 is reduced, and the inequality of the overlapped energization time is reduced, thus it is possible to ensure stability in controlling.

IPC: G11B7/085
Filed: 1989-02-01
Abstract: PURPOSE:To detect the accurate position of an optical head without increasing the weight of the optical head nor complicating the structure of the optical head by taking out a part of the light beam received from a light source to the outside of the optical head and receiving the taken-out light beam to the position of the optical head. CONSTITUTION:The light beam of a light source irradiates an optical recording medium 1 and the information is recorded and/or reproduced via an optical head 200. The means 103 - 109 are added to move the head 200 to the medium 1. Then a means 201 takes out partly the light beam of the light source to the outside of the head 200, and a means 202 receives the light beam to detect the position of the head 200. Thus it is not required to add an electric circuit to the head 200 for detection of the position of the head 200. Then the increase of the size of the head 200 itself can be avoided.

Title: Semiconductor memory
Inventor: HORIGUCHI SHINJI
IPC: G11C11/41
Filed: 1987-02-06
Abstract: PURPOSE:To speed up the clearing of a memory by providing a setting means, which sets all memory cells on a selected word line at a prescribed value at a time and a flag which corresponds to the respective word line and deciding whether the setting means is made to operate or not by the flag. CONSTITUTION:The flag Fi (i=0-M-1), prepared at every word line Wi shows that the prescribed value, for instance 0, should be set for all the memory cells Mi0-MiN-1 on the corresponding word line Wi. Accordingly, in order to clear the whole memory array 1, it is enough to set only all clear flags F0-FM-1. Here, when the word line Wi is selected, when the corresponding clear flag Fi is set, the setting means operates and sets 0 for all the memory cells Mi0-MiN-1 on the Wi and afterwards the clear flag Fi is reset. Thus, the clearing of the memory array 1 can be executed at high speed.

IPC: B41J19/18
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To obtain correct print results when printing is resumed after an error related to papers is resolved. SOLUTION: A position of an ink head when an error occurs is detected and stored in a RAM (steps S13 and S18). When the error is a paper out (paper lack) error, the ink head is once returned to a cap position, and then brought back to a memory position of the RAM by resolving the error (steps S14, S15, S21 and S22). In the case where the error is a paper jam (paper clog) error, the ink head is returned to the cap position when the error is resolved by removing the clogging paper and thereafter, the ink head is returned to the memory position of the RAM (steps S19-S22).
